Near The Edge Of The Solar System, Voyager 2 Finds Magnetic Fluff

From Discover Magazine:

After three-plus decades of exploring the gas giants, passing the orbit of Pluto, and reaching points beyond, Voyager 2 has found something interesting near the edge of the solar system: surprisingly magnetic fluff. Researchers document their findings in this week’s Nature.

Of course, this fluff isn’t made from the dust bunnies you find under your bed, the ‘Local Fluff’ (a nickname for the Local Interstellar Cloud) is a vast, wispy cloud of hot hydrogen and helium stretching 30 light-years across [Discovery News]. Astronomers already knew this fluff was out there near the boundary area between our solar system and interstellar space. What surprised them is that the fluff is much more magnetized than they’d expected.

How To Create A Designer Baby

From Popular Mechanics:

Increasingly sophisticated genetic tests make it possible for parents to choose their baby’s traits. Here are three ways babies are born to specifications.

For just an extra few thousand dollars, women undergoing in vitro fertilization (IVF) could one day choose to have a baby boy with perfect vision, an aptitude for sports and a virtual lock on avoiding colon cancer. Fertility clinics in the U.S. currently offer not only to screen for diseases, but also to choose gender. They are not yet offering any further customization, but that could change as genetic mapping gets faster and easier.

The Lithium Rush

From Technology Review:

In the Bolivian Andes lies a vast salt flat that may shape the future of transportation.

Nearly four kilometers above sea level in the Bolivian Andes lies the Salar de Uyuni, the world's largest salt flat. But there is more to this ­surreal, moonlike landscape than meets the eye. Flowing in salt-water ­channels beneath the surface is the world's largest supply of lithium--and, possibly, the future of transportation. Lithium is the key ingredient in the lithium-ion batteries that will power the electric vehicles that will soon be rolling off production lines worldwide. Demand for the metal is expected to double in the next 10 years, and Bolivia, with an untapped resource estimated at nine million tons by the U.S. Geological Survey, is being called a potential "Saudi Arabia of lithium."

Top Scientists Share Their Future Predictions

Neo (Keanu Reeves) in a still from The Matrix

From Times Online:

From virtual brains and Matrix-like thought connections to disease-making bacteria, what the next decade could bring.

Nothing much is going to happen in the next 10 years. Of course, that’s not counting the diesel-excreting bacteria, the sequencing of your entire genome for $1,000, massive banks of frozen human eggs, space tourism, the identification of dark matter, widespread sterilisation of young adults, telepathy, supercomputer models of our brains, the discovery of life’s origins, maybe the disappearance of Bangladesh and certainly the loss of 247m acres of tropical forest.

As I said, just another decade really.

From The Telegraph:

What were the most exciting scientific developments of the past 10 years – and what comes next?

Colin Blakemore - Professor of Neuroscience at the Universities of Oxford and Warwick and president of the Motor Neurone Disease Association

"My scientific moment of the last decade came on February 12, 2001, when the journal Nature published the 'working draft' of the entire three-billion-letter sequence of human DNA. One third of that massively expensive international enterprise – comparable in its significance to splitting the atom, or discovering radioactivity – was produced at the Wellcome Trust Sanger Institute, near Cambridge.

Why Some Continue To Eat When Full: Researchers Find Clues

From Science Daily:

Science Daily (Dec. 28, 2009) — The premise that hunger makes food look more appealing is a widely held belief -- just ask those who cruise grocery store aisles on an empty stomach, only to go home with a full basket and an empty wallet.

Prior research studies have suggested that the so-called hunger hormone ghrelin, which the body produces when it's hungry, might act on the brain to trigger this behavior. New research in mice by UT Southwestern Medical Center scientists suggest that ghrelin might also work in the brain to make some people keep eating "pleasurable" foods when they're already full.

Why Men Cheat: A Year Of Philandering

From Live Science:

Like years past, this one has been a whopper for high-profile philanderers. Psychologists aren't surprised, as guys are wired to want sex, a lot, and are more likely than gals to cheat. The behavior may be particularly likely for men with power, researchers say, though they point out that despite the genetic propensity to sleep around, cheating remains a choice, not a DNA-bound destiny.

The list of powerful individuals whose marital transgressions came out this year includes Tiger Woods, David Letterman, former senator John Edwards and South Carolina Gov. Mark Sanford.

Flying Blind: The Disappearance Of Flight 188

From Slate:

You've heard of planes that vanished into thin air? Here's a truer, scarier story: On Oct. 21, 2009, two pilots flying from San Diego to Minneapolis vanished into cyberspace.

Their plane was fine. Ground controllers tracked it the whole time. The passengers and flight attendants in the main cabin noticed nothing unusual. And the pilots' bodies stayed planted in their seats as though they were flying the aircraft. But they weren't flying it. Their minds had been sucked into a pair of laptops.

War Is Peace: Can Science Fight Media Disinformation?

From Scientific American:

In the 24/7 Internet world, people make lots of claims. Science provides a guide for testing them.

When I saw the statement repeated online that theoretical physicist Stephen Hawking of the University of Cambridge would be dead by now if he lived in the U.K. and had to depend on the National Health Service (he, of course, is alive and working in the U.K., where he always has), I reflected on something I had written a dozen years ago, in one of my first published commentaries:

PETN - Hard To Detect And Just 100g Can Destroy A Car -- The Guardian

The science behind the explosive pentaerythritol trinitrate, used on Northwest Airlines flight 253 and by the 'shoe bomber'.

The explosive that nearly brought down Northwest Airlines flight 253 is extremely powerful, allowing terrorists to use only small quantities to cause enormous damage. And the colourless crystals of the substance, PETN or pentaerythritol trinitrate, are hard to detect if carried in a sealed container.

Technology Changes 'Outstrip' Netbooks

Netbooks are under pressure as tech firms concentrate on mobile computing.

From The BBC:

Rising prices and better alternatives may mean curtains for netbooks.

The small portable computers were popular in 2009, but some industry watchers are convinced that their popularity is already waning.

"The days of the netbook are over," said Stuart Miles, founder and editor of technology blog Pocket Lint.

As prices edge upwards, net-using habits change and other gadgets take on their functions, netbooks will become far less popular, he thinks.

From Live Science:

Sea urchins may use the whole surface of their bodies as compound eyes, scientists now suggest.

Although sea urchins don't have any problems avoiding predators or finding comfortable dark corners to hide in, they don't have eyes. The question then is how they see.

Genetic analysis of sea urchins has revealed they have light-sensitive molecules, mostly in their tube feet and in tiny stalked appendages found in among their spines. As such, "it looks like the entire surface of their bodies are acting as one big eye," said researcher Sönke Johnsen, a marine biologist at Duke University.
